Seamless Solar Compatibility, Supercharged
Meet the world's first 4kW solar charge controller. The BLUETTI SolarX 4K takes 150–500V from nearly any rooftop or ground array and converts it into safe, sub-60V charging for BLUETTI power stations—up to 4,000W. That means faster charging, more stored energy, and reliable power whether you're backing up your home, running an off-grid cabin, or building your own solar farm.
Scalable Solar Power, 4 kW to 12 kW
SolarX 4K lets you decide how much solar power fits your life. Use one unit to cover daily essentials, or scale up to three for your whole home. It connects to your existing solar setup via AC coupling, keeping BLUETTI's DC input ports free for extra panels, so you get more energy, faster, without tying up your system.
Apex 300+B300K+SolarX 4K

Love it
Size: 16 Fl Oz (Pack of 1)
I use nivea lotions. First time trying this. Wow! Light scent, super moisturizing. Not oily, soaks in really well. Good price, and quick shipping. Will purchase again.

high fragrance
Size: 16 Fl Oz (Pack of 1)
This isn't my favorite Nivea product. If you're looking for the same consistency as the blue tub, this isn't it. The fragrance is a bit strong for me, but it does moisturize well and does not leave you feeling heavy or greasy. I will keep using it until it is gone but not repurchase.

This butter body cream is simply delicious, the texture in the skin feels soft, easy to absorb, the smell is really soft it doesn’t bother me at all. Good moisturizer for dry skin.

Great lotion!
Size: 16 Fl Oz (Pack of 1)
My skin stays dry. I wash my hands numerously throughout the day and the outside of my left index finger is almost always dry or the skin splits from dryness. My elbows sometimes are really dry too. I love this lotion and the smell of it. It performs miracles on my dry skin, it's so good. I definitely recommend to those who suffer from dry skin not only year round, but at any time. I will warn you though that the jar is huge, so it's a lot.

HIGHLY RECOMMEND
Size: 16 Fl Oz (Pack of 1)
I’ve tried many lotions & creams for my rough elbows & dry feet. Soon after I applied this cream I was surprised to see how soft my elbows & feet were. I use this cream on my arms, legs, feet & hands, it has improved the condition of my skin dramatically. AWESOME cream!
